Serial 1650

Serial 1650 is a virtual duplicate of Serial 1661– the text of which may be found here – and the text of the serials is the same. The difference is that this serial was forwarded by FBI Headquarters to its field office in San Francisco after the original was received from its office in Mexico City.

Like the original, the reformatted copy was originally withheld under the National Security Exemption of the Freedom of Information Act.
